Abstract

A windmill whose mast formed by a lower vertical part (1) and a rotatable inclined upper part (4) to which is connected the rotor (5) formed by at least two blades (6) so as to be rotatable about a horizontal rotor axis A-A, wherein each blade (6) made of parallel extruded profiles (10) is coupled with a blade carrier so as to be tiltable about an axis parallel to said blade (6) and extending beyond the centre of gravity Z thereof, the axis of tilt crossing the rotor axis A-A at a distance therefrom, whilst means for resetting the blade towards the rotor plane are arranged on the carrier, whereby the blades will be urged out of the rotor plane at an increase in wind load so that the wind pressure on the blade decreases to an extent such that the same torque is ensured with a speed of rotation remaining the same.
